To mom, you should have *the* talk with your son early on. Forget the fairytails and bees and other assorted junk. Just be honest about sexuality, tell him about STD's and safe sex. Do not leave it to the school because no kid takes it seriously in there.
Masturbation is as normal as breathing. Further, it's physiologically necessary for a non sexually active male. Rather than punishing your son, please take this time to teach him about sex and appropriate places to relieve himself. There is no possible way you can keep him from masturbating.

Thank you everyone for your responses. So it's normal for a child of that age? And there are no health risks?
Yes, it's completely normal for a child that age.
Health risks? None whatsoever. In fact, it's good for both phsyical and mental health. It's good for the heart as It lowers blood pressure and it releases (for empaths) oxytocin, a chemical that helps you relax. :)
Well he played with his penis and it felt good. Let him know thats something frowned upon in public and must be done in the confines of that bathroom, shower or his bedroom. Also you need to buy him some baby wipes.
When he gets older teach him to masterbate into condoms. That way he'll get good at putting condoms on and probably won't get a girl pregnant because of his excellent masterbation experience. This paragraph was a joke.
Use the search box above to check out the doc's website for anything on masturbation. You really need to get your head straight on this.
Why would you even think of punishing your son for that? It's his private business, not yours.
